We consider the statistical experiment given by a sample y(1), . . . , y(n) of a stationary
Gaussian process with an unknown smooth spectral density f. Asymptotic equivalence,

ESTIMATING SPECTRAL DENSITY FUNCTIONS ROBUSTLY
robustness spectral density function AO-model
2009/2/25
We consider in the following the problem of robust spectral density estimation.Unfortunately, conventional spectral density estimators are not robust in the presence of additive outliers (cf. [18]). I...
Estimation of the spectral density of a homogeneous random stable discrete time field
homogeneous stable fields spectral density estimate
2009/2/23
In earlier papers, 2π-periodic spectral data windows have been used in spectral estimation of discretetime random fields having finite second-order moments. In this paper, we show that 2π-periodic spe...
We propose two estimators of a monotone spectral density, that
are based on the periodogram. These are the isotonic regression of
the periodogram and the isotonic regression of the log-periodogram.

SPECTRAL DENSITY CORRECTION OF A SIGNAL AT FREQUENCY VARIABLE TRANSFORMATION
spectral density frequency transformation finite energy
2010/1/12
The goal of this paper is to determine analytical expression for the spectral density function of a signal, affected by a known frequency transformation, which do not modify the process energy. Such t...
